Indicator-based methods are able to provide a simple and reliable way to assess the level of fire risk of existing constructions. While many of these methods were not developed for cultural heritage assets, those that were often involve indicators connected to provisions defined by standards that are only valid in certain countries. As such, a method with the required versatility to analyse the fire safety of cultural heritage assets is still needed. Developing a method with the necessary characteristics requires a prior review of existing approaches to understand their strengths and weaknesses. A review of existing indicator-based methods for fire risk assessment is, therefore, presented, covering methods applicable to built cultural heritage assets and other types of constructions. In addition, the review also analyses existing fire safety guidelines and recommendations dedicated to cultural heritage assets. As an outcome, the review proposes twenty-two vulnerability indicators grouped into four categories that can be used to develop a fire risk assessment method dedicated to built cultural heritage assets. The review also establishes a classification of cultural heritage assets according to four classes that focus on their fire vulnerability and discusses the applicability of the proposed indicators.

基于指标的方法能够提供一种简单可靠的方法来评估现有建筑的火灾风险等级。尽管其中许多方法不是针对文化遗产资产开发的，但那些方法通常涉及与仅在某些国家/地区有效的标准所定义的规定相关的指标。因此，仍然需要一种具有所需多功能性的方法来分析文化遗产资产的防火安全性。要开发具有必要特征的方法，需要对现有方法进行事先审查，以了解其优缺点。因此，对现有的基于指标的火灾风险评估方法进行了回顾，涵盖了适用于已建成的文化遗产资产和其他类型建筑物的方法。此外，审查还分析了针对文化遗产资产的现有消防安全指南和建议。结果，该审查提出了22个脆弱性指标，分为四个类别，这些指标可用于开发专门用于建筑文化遗产资产的火灾风险评估方法。审查还根据四个类别对文化遗产资产进行了分类，重点是火灾的脆弱性，并讨论了拟议指标的适用性。
